in material compressing machines and has particular relation to that class. of machines adapted for receiving materials in more or less comminutcd form and small pieces, and

tightly ci'u'npressing and forming the same into a compact body, mass, stick or bar, the compressed composite piece, or. sticlnbeing "formed into suitable lengths wrapped and bound by a holding means.

The machine is especially well adapted for the compressing of saw dust, shavings, chips and the like into solid masses or sticks and binding wires about the same.

A machine otthis general type has been employed heretofore for such purposes but various means were employed for accom plishing the diii'erent steps inltreating the compressed material, making a complex mechanism of themacl'line.

It is an object of the present invention, among other things, to provide a machine of this general character, in which, however, the compressed material may be separated into suitable lengths, twisted for fastening a wire about the same and have the wire cut. through the 'instrnmentality of one member, which is operable in conjunction with the plunger which compresses the materials. i

it is, also, a further object of the invention to provide such a device in which a single cam member maybe used and formed with cam surfaces adapted to actuate the various parts of the mechanism after the material has been compressed into a com posite piece or stick of a desired length.

.Vith these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described.

in position for severing the i will now be specifically described reference being had to the accompanying drawing in which 18 indicates the frame of the machine, which is provided with a platform 19 adapted to carry the forming die 20 and the receiving hopper 21 of the compressing mechanism. The upper portion of the frame 18 extends considerably above the plat form 19 and has bearings therein for a shaft 22, which carries a gear wheel 23 and a crank disk 24. The said crank disk 24 is provided with a wrist pin which engages a pitman 25 for operating it as the shaft 22 is rotated by the gear 23. The lower'end of the pitman 25 is connected with a plunger cress head 26, which moves in guides 27 upon the frame 18. The said cross head 26 carries a compressing plunger 28, which is adapted to force the materials to be compressed, into the hopper 21 and the die member 20; The said cross head 26 also carries a laterally projecting arm 29, which is arranged to operate the moving member,

" by belting 33 with any suitable source of power not illustrated. The pulley 32 preferaloly runs freely upon the shaft 31 and may be connected therewith when the machine is to be operated by the manipulation of a clutch, preferably such as is illustrated upon an enlarged scale in Fig. 18 of the Such clutch usually comprises a friction disk 34 adapted to bear upon one side of the pulley 32. The said disk is splined to the shaft 31 as is also an adjacent cellar 35 which carries clutch operating levers 36. The outer ends of the levers 36 have adjustable screws 37 for bearing against the disk 34 while their inner ends approach the shaft 31 and are adapted to be separated by a cone sleeve 38 loosely mounted ufpon the shaft 31. A hand lever 39' pivoted upon the frame and having a yoke portion 4Q engaging studs 41 carried by the said collar 38 is provided for operating said cone. It will be readily understeod that, when the lever 39 is moved so as to cause the cone 38 to operate the levers 36, the friction disk 34 will be caused to A press tightly against the pulley 32 whereby the said disk will be turned with the pulley and its',movement will be imparted to the shaft 31.- c

The platform 19 is formed with an opening therein for receiving the die member 20 Said die member is preferably made up of two approximately semicylindrical sections 42 and 43 the upper ends of which are formed with over-hanging flanges 44 and 45 which rest upon the upper surface of the platform 19. The die section 42 is preferably rigidly held in positionand may be secured to the platform 19 by one or more bolts 46. the die is preferably made to rock slightly upon the edge 47 formed upon the plat form 19. The opening in the platform is cut back to a slight extent from the upper edge 47 and the under side of the flange 45 is slightly beveled, as clearly shown in Fig. 9, to permit of the slight rocking action which is sometimes needed in the said die section 43. Such need arises when the materials compressed become, too tightly wedged within the die and the slight separation of the die sections, caused by the rocking of the section 43, will relieve the tightness and permit the materials to be forced on through the die. The lower ends of the die sections are properly supported, the section 42 resting against an abutment bolt 48 carriedby the frame 18. The said bolt carries abutment nuts 49 which may be adjusted to bear against the end of the section 42 and thus give it positive support. The lower end of the opposite die section 43 preferably rests against an adjustable abutment bolt 50, the inner end of which engages a slight socket 51 made in the die section 43. The outer end of said bolt is provided with a hand lever 52, by which the bolt may be turned upon its threads for easing up upon the section 43 when there is danger of the mate rials compressed sticking within the die. The upper flanged ends of the die sections 42 and 43 are movably connected by curved strips 53 bent to fit upon the peripheral portions of said flanges and having studs 54 projecting into holes formed into edges of i the flanges 44 and 45. Such connection is found to be sufliciently firm to hold the die sections at the top and yet permit of the rocking of the member 43 for operating the lower portions of the die.

The die sections are preferably formed with lining sections 55 and 56, the inner surfaces of which form a cylindrical passage just large enough to receive the plunger 28. The hopper 21 is mounted upon the upper ends of the die sections 42 and 43 and the contracted end thereof is made to just fit over the opening in the die lining sections'55 and 56.

As the loose materials, which are to be compressed, are continually driven into the die they will be formed and compressed into a continuous stick within said die, which is forced downwardly through said die as new material is compressed at the top by each reciprocation of the plunger 28, The materials forming this stick are preferably The opposite section 43 of I in Fig. 19.

bound together by binding wires so that in the case of sawdust, shavings etc, compressed to form a proper fuel. the small particles will not be likely to work loose or become separated before it is desirable; In placing a binding means around a stick of suchlloose material, also, it is found that unless the binding means or wire is thoroughly e1nbedded within the stick that the shavings will quickly curl outwardly from beneath the wire when placed in a fire and will thus permit of a too rapid disintegrationit'or the formation of a goodfuel. difliculty the die is provided with knife pieces 57 and 58 mounted opposite each other in slots formed upon the inner surfaces of the lining. sections and As the material is forced through the die the knife pieces will form deep kerfs in the opposite sides of the stick as indicated at 59 Auxiliary shorter knife pleces are, also, preferably pro 60 and 61 vided within the die and in alinement with the knife pieces 57 and :38, said auxiliary pieces keeping the kerfs open for the reception of binding wires 62 Said binding wires enter the die passing from spools Gathrough openings 65 formed in the walls of the die sections and are forced into the kerfs 59 in the composite stick of material by small knife pieces 66 and 67 carried near the lower end of the die sections. Said latter :knife pieces preferably do not extend into the die quite as far as the other knife sections above and their inner edges are made more blunt and at least as wide as the wires 62 and .63 so as to properly press them into place in the kerfs of the completed stick, as Will be readily understood by reference to Fig. 9 of the drawing. In order to prevent the lining sections 55 from slipping downwardly, they are provided with shoulders 68and 69, which engage interior shoulders TOzand 71 formed. near the lower ends of thedie sections.

Cap screws 72 are, also, passed through the walls of the diesections and the lining sections to prevent the sections from turning with respect to each other.

The fixed die section L21 has journalcd thereon, a wheel 7 3, the periphery of which provided with sharp serrations adapted receiving the stick of material compressed,

for breaking it off in suitable lengths, twist lng and securmgthe bmdmgw res and for To obviate this cutting off the said binding wiresafter they are twisted. It isan important feature of the present invention that these. operations are accomplished through the agency of a single movable member controlled by the cross head of the machine andsuch feature constitutes one of the novel parts otthis. 1nvention.

Located. below the die mechanism is a mechanisnr for separating the sticks of ma;

tcrial. compressed into proper lengths, and

for twisting the binding wire thereon;

This mechanism is made up of anouter cyls inder (i, which has a bearing 111 a collar 75 engagingthe said cylinder at a point near form 7 9 whichis formed in the frame below the platform 19. The lower ends of the standards'l'? are provided with racks havmg rackteeth adapted to engage and mesh with the teeth of rocking se ments 81. Each of the segments 81 are journaled upon supi porting pivot bolts 82, which are secured to adjacent upright portions of the: fraine18,

as clearly shown in Fig. 1 of the drawing.

The upper corners of both the segments 81 are pivotally connected to a cross bar 83. and a thrust bar 8% rigidly connected with said cross bar 83 projects outwardly at right ani glcs thereto and engages a guide slot or hearing 85 formed 111 a guide plate 86, which 1s mounted upon the front of the machine.. The said thrust bar 84. has a laterally pro ecting pin 87 carrying an ant1fr1ction roller, said roller being adapted to"en-.

gage and move in cam patlrSS formed in a cam member 89. The said cam member 89 moves vertically in suitable guide ways upon the front of the machine and the thrust bar S lis thus moved at suitable intervals for rocking the segments 81 and loweringlthe twisting member as well as for raisingit again.

Returning to the twisting member proper, the outer-cylinder .74; has mounted within it the semi-cylindrical sections 90 having supporting flanges 91 at their upper edges. The

said sections donot quite fill the interior of the cylinder 7% and may thus be slightly spread when the stick of compressed material is forced through them. C-springs 92 are .mounted in annular recesses 93 formed in the upper end of the cylinderfll. and have their free ends bearing upon, the

sections 90 so as to tend to force them toward each other with a yielding pressure, as. will. be clearly understood With. reference to i Figs. lland 12 of the drawing. The sections 90 areprevented from turning with re spect to the cylinder 74 by means of lug i turned for rotating the shaft 106.

within the supporting yoke 75 a sprocket ring 96 is rigidly secured to the lower end of the cyhnder 741. Said sprocket ring 1s engaged by a sprocket chain 97, wh ch also engages sprocket teeth 98 formed upon a clutch cup member 99. The cup member 99 is normally supported above and out of engagement with a clutch cone 100, which is rigidly secured to a vertical shaft 101 journaled in bearings 102 and 103, which project from the frame 18. The shaft 101 is kept in continuous rotation when the machine is in operation, being driven by a beveled gear 10a secured to its upper end and meshing with a beveled gear 105 carried by a horizontal shaft 106. The shaft 106 is mounted in bearings 107 and 108 and has secured to it a sprocket wheel 109 by which it may be The sprocket wheel 109 is connected by a sprocket chain 110 with a sprocket wheel 111 which is rigidly secured upon the power shaft 31. kept in continuous rotation and when it is desired to actuate the twisting member it is only necessary to lower the clutch cup member 99 so as to engage said cone.

' The raising and lowering of the cup member 99 is under the control of a rock shaft 112, which is supported upon projecting bearing bars 113 mounted upon the platform 79. Said rock shaft is provided with a yoke member 11 1, which surrounds a hub 115 upon the upper side of the cup 99. The yoke member is provided with inwardly projecting pins 116, which engage an annular groove 117 formed upon said hub 115. When the yoke member 114: is lifted by the rocking of the shaft 112 the cup member 99 will be raised and disengaged from the driving cone 100. When the rock shaft 112 is moved so as to lower the yoke member 114 the cup 99 will be lowered into engagement with the cone 100 and will be turned thereby for rotating the twisting member through the agency of the sprocket chain 97.

The movement of the rock shaft 112 is effected by a lever 118, which projects beneath a cam 119 carried by a second or counter rock shaft 120. The counter rock shaft is mounted in bearings 121, which project outwardly from the platform 79 and the said count-er rock shaft is actuated by means of an arm secured to one end thereof and projecting downwardly so as toengage the end of a thrust bar 123, which is movably mounted on said platform 7 9. The lower end of the arm 122 is usually rounded at 12 1 and loosely engages an inclosing strip 125, which is fastened upon the end of the thrust bar 123. The forward end of the said thrust The clutch cone 100 may thus be 2 bar extends to a point adjacent to the cam member 89 upon the front of the machine and is adapted to be forced inwardly by a cam projection 126 carried by said member. The body portion of the said cam member 89 is preferably composed of a rectangular bar 127, the lower end of which passesthrough a bearing at'the base of the frame 18, while the upper end passes through and is guided by a bearing in a bracket 128 projecting upon the upper part of the machine. The cam projection 126 issecured upon one side of the bar 1 7 and its lower end is beveled 129 so that as the bar 127 descends the bevel will engage the front end of the thrust bar 123 and thus force the same inwardly for separating the members of the clutch. In order to permit the said thrust bar to come forwardly again when it is desired to bring the clutch members together, a trip bar 130 is pivotally mounted upon a standard 131, which is secured upon the platform 79, just one side ofthe thrust bar 123 when occupying its normal position. The trip bar 130 is provided with an inclined cam projection 132, which extends into the path 4 of a correspondingly inclined cam projection carried by a block 126 fastened to the said bar 127 and interposed between the same and the cam projection 126. The ar rangement of the parts will be clearly understood by reference to Figs. 1a and 15. The standard 131 has a lateral projecting arm 13%, which prevents the rising of the thrust bar 123 from the surface of the platform 79. spring 135 connected with the trip bar 130 at one end and with the standard 131at the other end tends to return the said trip bar to its normal depending position. When the bar 127, constituting the bodyportion of the cam member, is elevated the cam projec tiOn. 133 will force the cam projection 132 to one side, causing the trip bar 130 to move the adjacent end of the thrust bar 123 laterally and out of engagement with the cam projection 126, thus permitting the yoke member 114. to descend and the clutch cup member to engage the cone, as heretofore described. As soon as the projection 126 rises above the thrust bar 123 a spring 136 will draw the said thrust bar 123 against the base of the standard 131 again so as to be in thepath of the cam 129 when it descends.

Cooperating with the mechanism of the clutch is a band brake 137, one end of which is rigidly secured to a bracket 138 fastened to the under side of the platform 79 as clearly shown in Fig. 17 The hand brake passes around the outer periphery of the clutch cup member 99 and is adjustably secured to alever 139. The said lever 139 is pivoted to a standard 140 which'rises fromthe base of the machine and the upper end of said. lever is bent to one side at 1&1, so as to overhang the free end. of an arm 142, which is carried by and rigidly secured to the rock shaft 120. A spring 143 connected with the upper portion of said lever 139 and extending to one of the bearing arms 113, normally tionary immediately after the separation of the clutch members; The operation of the band brake and the clutch is thus dependent upon the movement of the thrust bar 128 and the rock shaft120. j

The lowering and turning of the twisting member 7-1 operates to break off the stick of compressed material at the lower end of the die and to twist the wires 62 and 63 between the broken ends of said stick, asindicated in Fig. 20. While the twisting member and die are thus separated, .a cuttingpdevice is thrust between the said members and caused to. sever the twisted wires, as also indicated in said Fig. .20. The cutting device is made dependent upon the movement of the cam member at the front of the machine and the said cam member is provided with a cam path adapted to engage an anti-friction roller 1&6 carried by thrust bar 147. i The.

outer end of the said thrust bar engages a guide bearing 1 18 in the adjacent plate 86 and is connected at its. inn-er end with a cutter blade 1 19. The cutter blade travels in a guide formed upon a standard mounted on the platform 79 and its inner edge is inclined and beveled to form a cuttingedge which cooperates with an adj acent.

blade 151, which is pivoted to the cutter blade 1-19. The blade 151 is provided with an arm 152 having a curved slot therein, which engages a pin 153 carried by anarm 15 1, which is secured totlie frame 18. The shape of the arm and the slot and the arrangement of the pin 153 is such that when the blade 1&9 is thrust inwardly the cutting portions of .the blades will be brought to-. gether around the wires ,andbe made to cut the same with a shear likejaction. Since the cutting of the wires isnot desired until the stick of compressed material has been broken and separated and thewires have been properlytwisted, the campath 154: is shaped, as shown in Figs. 3 and 7 of the drawing, having a curved portion 155, which carries the antifriction roller 14:6 inwardly for a part of its travel and a returnpath 156 is provided which operates when the cam member descendsagain to finish the inward stroke of the knife blade and make a quick return thereof to its normal position after the wires have been cut. The curvature of the portion of the cam path is such that the anti projection .157 arranged in thecentral po friction ro-lleris carried beneath anlinclinedl tion of the cam path. When the cainmemi ber descends again the "said anti-friction roller will thus be engaged by said inclined projection and forced inwardly therebyt. 'lhe movementof the cam member is made chine. The arm 29 moves so that its outer dependent upon theconnection of the bar end travels to one side of saidbar .127 and an abutment piece 160 is secured to the side of said bar projection j into thejpath of said 211-11129. whereby the arm will depress or force downwardly the cam member .to the desired distance. Thecam member will, however,

remain in said depressed position and will, not rise ltll thearm 29 agalnuntil a trip plate 161., which is movably connected with the bar 127 by pivoted links 162, is thrown outwardly above the said arm 29. Said trip piece 161 lies in a recess in the side of the i a bar 127, so that the arm 29. may pass fthe same, until the desired length of composite stick has been formed: by tlie plunger; A spring 163, connected with aflange161 0f the trip piece 161and fastened, also, to the 1 arm 127,. normally tends to .force the I trip piece into armj engag ng 13051131011. actlon is normally. prevented, however, by

a latch member 165. Said latch nember iis pivoted upon one side of the bar 127 and has one end turned outwardly so as to be capable of engaging a recess or hole 166 formed in the flange 16%. A spring 167 normally keeps the latch lnengagement with said hole. The

lower end of the latch is turned injthe oppo-i site direction so as to. be engaged the i inclined surface 168 ofa cam block 169,

which is pivoted upon a trip rod 170. Said cam block is limited inits movement in one direction by a. pin171 and islnormally held against said pin under yielding pressure by means of a spring 172 carried by said trip rodlTO. The upper end of the trip rod is adapted to slide in a guide bearing formed upon the bracket 128 while the lower end of said trip rod is pivotally connected with one end of a trip lever-173. Said triplever is pivoted upon the platform 19 in suchaposition that its inner curved end l7 1will lap upon oneedge of the serrated wheel 73l1ereinbefore described and set forth as adapted it to engage the composite stick of compressed material. The said serrated wheel 7 3is proid-cd with projecting pins 175 and 17 6 ex-, tending from one of its faces. As the wheel 7 3 is turned by the downwardly forced com- 1 pressed material in the die, the pins 175 and. 176 will successively engagdthe trip lover 173. Thus when thedesiredlength" of 1 stick inthe die has been attained thetrip lever will be operated to mu the tripbar 170 downwardly, which will cause the cam block 169 to force the latch 165out of en portion of the machine frame.

y will, also, force the cam member downwardly again by its engagement with the abutment projection 160. As the cam member descends the trip block 169, which is beveled at its upper end, will be sprung to one side of thef end of the latch 165. The trip piece 161 is returned toits latched position when the cam member reaches its highest point, by

means of a spring pressed bar 177, which is,

mounted upon the bracket 128. Said spring pressed bar 177 forcesthe'trip piece 161 inwardly until the'latch 165 springs into the opening 166 for locking said trip piece in Dlace.

jlln'order to prevent the cam member from descending under the action of gravity and before the arm 29 positively depresses the same, a brake device is applied tothe lower end of the bar 127, as clearly shown in Figs. 7 and 16. The said bar 127 passes between friction pieces 17 8 and 179 carried by parallel bars 180, which are secured to the lower A bolt 181 connecting the free ends of said bars may be tightened to the proper degree for exerting enough pressure upon the said bar 127 to revent its accidental movement, or any mo ion thereof except under the impulse of the arm 29.

The operation of the machine will be readily understood from the above description and neednot be set forth with greater particularity at this point. A general ref erence to the operation will be suflicient in connection with said description. The machine is set in operation by. the throwing of the clutch disk 34. The plunger 28 will thusbe caused to continuously reciprocate. The particles tobe compressed, as for instance saw-dust, shavings, chips, or the like, are fed into the hopper 21 and the plunger 28 continuously forces charges thereof into the die, and as the stick of material in the die lengthens under the action of the plunger 28 it will be forced between the wires 62 and 63 and will, also, turn the serrated wheel 73. When a stick of suflicient length has been produced, the wheel 73 will trip the lever 173 and cause the trip piece 161 to be thrown outwardly and into engagement with the arm 29. The principal cam member of the machine will thus be carried upwardly by the arm 29, the various cam surfaces of the member causing the descent of the twisting member for the separation of the stick of material, the bringing together of the clutch, members for twisting iue a'i the stick and the wires around it, the brake 'tracted to their inoperative positions.

actlon of the parts is thus entirely automatlc having been at the same time released, and further, the operation of the cutting mechanism for severing the twisted wire between the separated ends of the composite stick. The descent of the cam member that above described accomplishes the last portion of the wire cutting operation as above set forth. Upon the complete return of the cam member to its lowermost position, the twisting member will have been raised to its position adjacent to the die, the clutch members will have been separated and the hand brake tightened to hold the cup member stationary and the cutting blades will have been re- The when the machine is running. The completed sticks with the wire twisted at both ends thereof will force each other out of the lower end of the twisting member in succession.

llhile the machine has been shown with only one compressing plunger and cooperating parts, it will be evident that by providing other cranks upon the main shaft, that other plungers may be used with their cooperating parts for doubling or further increasing the capacity of the machine, all within the spirit and scope of the invention.
